I think you misread my post. I am asking if someone successfully built wxWebConnect for MinGw. I read somewhere that kirix people do not use MinGw and to encourage them trying it, i gave a quick installation how-to. From what i have read, nobody successfully used wxWebConnect with MinGw so far...

As the answer is in the post you link to, I would expect this to be an alignment issue. XULRunner will have been built with MSVC++, so the alignment in a version of WebConnect built with MSVC++ should be the same. On the other hand, there is no guarantee that the alignment in MinGW will be the same as the MSVC++ alignment (if you built XULRunner itself with MinGW you might have a better chance of it working, but I have no idea of whether doing this would be easy or hard).

MinGW is a tier 3 platform for Mozilla (https://developer.mozilla.org/en/Suppor ... igurations). What this means is that there is someone who tries to keep it working, but it's not guaranteed to work at any time. It also notes that "some features are disabled because they require MS COM or the w32api project doesn't expose the necessary Windows APIs". It doesn't elaborate on which features these are, so I don't know whether they would affect wxWebConnect working. Nor do I know if 1.9.2 is one of the versions where a MinGW compile would work.

I think it is better to just use MSVC++. It is the standard C++ compiler on the platform, which is why it is used in the official builds of Python, Mozilla and other prominent open source software. There is no problem developing free software with it (seeing as I use both Python and the standard wxWebConnect with XULRunner, I do it).
